OCR or Number recognition in lightroom

Hey all, I'm in need of a program that can search for bib numbers within photos much like how facial recognition works in Lightroom, and add the bib number to the tag file in the exif.

I shoot fun runs/walks and upload 500-200 photos per event but I have no way other than manually to add bib numbers to the tags files, does anyone know if there is an add on for lightroom that could do this??

I too would be interested.

Maybe...
